Thanks a lot chewy for your response, that was very informative.
I think I truly have bent some rules with the normal approach or the logical methodology, but still I think I might have achieved some results. ASUS SUCKS for instance.
I heard that the TYG03 might be problematic with some drives, but I don't think my burns with the TYG03 (burned at 16X and tested at Maximum speed - point taken about the testing speed -) looks problematic, don't you agree?
I also like the scans of the Lite-On and the BENQ DW1800, what do you think?
For someone that might come reading this thread.
I also tried to disable the WOPC and the Soild Burn options in order to achieve a higher burning speed, It did matter with speed, but it came at a cost with quality.
